DATA SHEET
Pyrogel® XT FLEXIBLE INDUSTRIAL INSULATION FOR HIGH-TEMPERATURE APPLICATIONS Pyrogel® XT is a high-temperature insulation blanket formed of silica aerogel and reinforced with a non-woven, glass-fiber batting. Silica aerogels possess the lowest thermal conductivity of any known solid. Pyrogel® XT achieves this industry-leading thermal performance in a flexible, environmentally safe, and easy-to-use product. Ideal for insulating piping, vessels, tanks, and equipment, Pyrogel® XT is an essential material for those seeking the ultimate in thermal efficiency.

Advantages
Thermal Conductivity†
Superior Thermal Performance Up to five times better thermal performance than competing insulation products
ASTM C 177 Results
Physically Robust Soft and flexible but with excellent springback, Pyrogel® XT recovers its thermal performance even after compression events as high as 100 psi Shipping and Warehousing Savings Reduced material volume, high packing density, and low scrap rates can reduce logistics costs by a factor of five or more compared to rigid, pre-formed insulations Simplified Inventory Unlike rigid pre-forms such as pipe cover or board, the same Pyrogel® XT blanket can be kitted to fit any shape or design
